The testing results measured at the combine are used to inform recruiters of players' athletic attributes and skills heading into the AFL Draft, which is held in November. Recruiters also have the opportunity to interview participants whom they may potentially want to draft. Clubs are able to send a representative to the combine, where they are able to conduct a medical screening on participants. This screening gives clubs an idea of a player's past injuries and future injury concerns.[3]

To be eligible for the AFL Draft Combine, a player must receive at least 5 nominations from AFL clubs. Leading into the combine, AFL recruiting managers are expected to submit a list of 70 players from the draft pool whom they would like to screen at the national combine. Approximately 100 invitees attend the draft combine. Draft hopefuls who don't receive enough nominations for the national combine but still receive 3 or 4 nominations have the opportunity to attend their respective state screening.[4]

Players who are overlooked for the national combine may be invited to attend a state-based combine, where similar testing is done.

Players are to finish a 20-metre leg before the sound of the beep; they continue to run back and forth as the time in between each beep gets shorter. The test starts at level 1 and finishes at level 21. When a person fails to make the line before the beep, they no longer are allowed to continue.[6]

The player starts standing upright; once they pass through the gates, the player is to navigate around a series of poles (without touching them or knocking them down) and reach the finishing gates as quickly as possible.[6]

This is to measure a player's speed. The individual being tested begins in a crouched position. They are then to sprint as fast as they can up to 20 metres. Sensors are used to measure the time taken to the 5m, 10m and 20m mark. Each player is given 3 attempts at this, with the quickest time being recorded.[6]

In this test an instrument called a vertec is used to measure a player jumping off one leg from a running start. The player being tested aims to hit the 'fingers' on the vertec as high up as possible.[6]

This test was devised by Nathan Buckley and is used measure a player's kicking efficiency over six kicks. Six targets are set out at distances of 20, 30 and 40 metres. An official is designated to request a target at random and call the instructions out to the kicker. The kicker then proceeds hit the target. Each kick is given a score from one to five (five being the perfect kick).[6]

Matthew Lloyd designed this test to measure how well a player takes possession of a football and is able to dispose of it using a handball. Three targets are set up on both the left and right sides at distances of 6, 8 and 10 metres. The test starts with an official either rolling or throwing a football at the player; an instruction of what target to hit is then called out by the official. The player then attempts to handball the ball at the target. This is done six times and a score from one to five is allocated for each handball.[6]

This test was constructed by Brad Johnson and measures a player's accuracy kicking for goal. This test takes place on an oval with four markers placed at different angles and distances to kick from. Five kicks are taken in total: two set shots, two snaps (one left and one right) and one kick on the run. A score is then derived from the number of goals and behinds a player kicks.[6]

The AFL has increasingly looked to expand the game beyond Australia in recent years. It is estimated over 100,000 people participate in the sport outside Australia.[9] The Australian Football International Cup takes place every three years in Melbourne, where teams from 18 countries compete against each other.[10] The growth of the game and the prospective talent overseas has led to the AFL establishing combines internationally.

The US AFL Combine is currently held at IMG Academy in Florida. All 15 participants from the 2015 combine were from a college basketball background. Each year a minimum of two of the group will be chosen to partake in the AFL National Combine held in Melbourne. Eric Wallace, Mason Cox and Jason Holmes are all AFL listed players who are former US Combine graduates.[11]

The European Combine is held in Dublin and overseen by AFL International Talent Manager Tadhg Kennelly, a former player for the Sydney Swans who was originally drafted from Ireland. Among those who try out, a large proportion are Gaelic footballers. The skill set of Gaelic football is considered similar to that of AFL.[12] The two best-performing participants at the combine are then given the opportunity to attend the AFL National Combine. Sean Hurley, Paddy Brophy, Daniel Flynn, Ciarán Byrne, Ciarán Sheehan and Cian Hanley are some notable people who have previously attended the combine.[13]
